There are loads of great characters in Twin Peaks, but to my mind there are also some potentially great characters who also could've been given more prominent roles.

My top 3 would be:

Johnny Horne - with the Indian get-up you feel he really could've done something interesting, but he remains very much a bit-part (even during Ben's Civil War scenes)

Sylvia Horne - first time I watched TP, I didn't realise Ben's wife was still around. Would've been interested to see how she coped with Ben's infidelity (she must have at least suspected it) As far as I know she was scripted into some more series one scenes which didn't air (maybe didn't even get shot), but then vanished completely until the final episode.

Ronette Pulaski - after she comes out of her coma, she barely gets mentioned. Surely there was potential for more Black Lodge/Bob incidents?

 Any other minor characters you would like to have seen more of?

More Sarah! Can´t belive we saw nothing of her after Lelands death

Ditte 

more of the bikers that we see talking in the Roadhouse in the pilot, e.g. the boy who takes Donna to James.

 more of ronette.

This would look good on your wall.

-Noah- 

More James Hurley....BWAHAHAHA!!!

No no, Im just messin'. We saw too much of him.

 More Albert and Gordon. I mean Albert was in it a good bit, but he kept vanishing and coming back. When I first saw the second season, I thought Albert was going to be aroung for the hole thing. But No.

But mainly I wanted to see more Toad. He was the life and soul of that show. And nobody ever gave him credit for it. Not even one lousy nomination.

That god damn trailer's more popular than Uncle's Day in a whorehouse!

Beware of BOB

When I call out no one can hear me,when I whisper he thinks the message is for him only..my little voice inside my throat,I always think there must be something that I've done or something I can do...But no one no one comes to help,he says,a little girl like you...

Yeah...I agree,jasper!!!

Laura is the most important link to Twin Peaks!To me...she is the main character in the whole show! What does appear in our mind at first when we hear Twin Peaks???...Definitely the image of Laura!

Beware of BOB

OBVIOUSLY..... 

GORDON

<---------------

You remind me today of a small Mexican Chiwahwah.

I dont know how to spell chiwahwah, but I think Gordon Coles point was very valid. 

I think they were on an equal footing, they were just different. They made a great partnership, "Holmes & Watson" as Harry himself had said. As in one was the brilliant minded genius (Coop) and the other had to pay more attention to the more mundane aspects of things as well as pay attention to the rest of what was happening in the station, where he was still needed. (Harry.)

Anyway back on topic.

Sorry, but I disagree with the comments about both Sarah Palmer and Sylvia Horne. From what little we DID see of Sylvia, she seemed to just be boring, argumentative and have no backbone, trying to be the dutiful housewife when it was blatantly obvious that wasn't who she was at all. She only ever had converstaions with her family too. I don't know, she just seemed a bit one-dimensional to me. Which I think was the point of her character.

As for Sarah, well, it's not entirely true we didn't see her again - she was in the final episode when she spoke to Major Briggs. the thing with Sarah was, when we saw her in that episode, she was (understandably) a completely nervous wreck. So would it have been worth showing more of her? Because all she would have been doing would have been grieving along for Leland and Laura and maybe getting the odd shot. I certainly don't think she is a boring character, just maybe she wouldn't have had much to say that was relevant to the latter part of series two and that could be why she was focused on less.

Now, my three I would have like to have seen more of.

1) Thomas Eckhardt - I am amazed he has not been mentioned yet. He was in so few episodes and yet was such a fantastic character. Yes, he was bad, but he was right up there with Windom Earle in the "evil" stakes. If he had stayed in Twin Peaks and not bothered with (or not been killed off by) Josie, it would have made a fascinating storyline if he had moved/stayed in the Peaks and made Catherine Martell's life a living hell to see how pissed off Andrew got, and especially if the two of them started their rivalry up again, it would have been brilliant to watch, definetly more so than the Marsh crap.

2) Definetly Ronnette Pulaski - In my view, she IS the Laura that lived, if that makes sense. When I first saw the Pilot Episode, I was sure she was going to be a regular character, and the fact she was such a brilliant actress and that wasn't used more seemed (and still does), such a waste to me. She was only in 4 episodes, and FWWM. Granted, she was in a coma for most of series one, so they couldn't use her then, but when she woke up, her flashbacks were so fascinating! Then she saw BoB, then could sort of half-talk and then we never see her again until the final episode where she seems almost fully recovered! So what I would have loved to have seen is just more about her in general. Like what led to her getting into the same bad habits as Laura, what kind of relationship she had with her family, who were her friends, how did she and Laura meet and most importantly, how did she recover so quickly in such a short period of time!
